Precision Series References
DESCRIPTIO
The LT
that combine high accuracy and low drift with low power
dissipation and extremely small package size. These se-
ries references use curvature compensation to obtain
low temperature coefficient, and laser trimmed precision
thin-film resistors to achieve high output accuracy. The
LT6660 will supply up to 20mA with excellent line regula-
tion characteristics, making it ideal for precision regulator
applications.
The LT6660 family of series references provide supply
current and power dissipation advantages over shunt
references that must idle the entire load current to oper-
ate. Additionally, the LT6660 does not require an output
compensation capacitor. This feature is important in
applications where PC board space is a premium, fast set-
tling is demanded, or total capacitance must be kept to a
minimum, as in intrinsic safety applications. Reverse-bat-
tery protection keeps these references from conducting
reverse current.
